DIR-AFT RIG FOR TRACTORS. I

' Specification of Letters Patent. PaJbQnted Ju 5 1922 Application filed January 11,1222." Serial in. 528,467.

To all whom it may concern:

Be it known that I, "WILLIAM DALE F. IeNnY, a citizen of the United States of America, and resident of Huntington, 1n the county of Huntington and State of Indiana, have invented certain new and useful Improvements in Draft Rigs for Tractors, of which the following is a specification.

This invention relates to improvements in draft rigs for tractors, and the objects thereof are, to provide a pivotal draw-bar and means for applying it in connection with a tractor at a point thereon ahead of the drive axle so as to counteract the tendency of the tractor to capsize backwardly as may occur when the load is hitched to the tail lug in the usual manner; and to provide means for adjustably positioning the coupling end of the draw-bar laterally at the back of the.

tractor so that the load will be trailed to one side or the ot ier thereof. Another object is to so construct the constituent parts of the device that they may be readily assembled and applied to a tractor.

These objects are accomplished by the construction illustrated in the accompanying drawings, in which Fig. 1 is a diagram of a tractor showing a side elevation thereof and the present invention included;

Fig. 2 is a plan view of the anchor and the draw-bar connected therewith;

Fig. 3 is a detail view on a larger scale showing a side elevation of the adjusting mechanism and rear support for the drawbar, there being parts shown in section;

Fig. 1 is a partial plan'view of Fig. 3, the section being on the line 14. thereof; and

Fig. 5 is a rear elevation projected from Fig. 4:.

The characters appearing in the description refer'to parts shown in the drawings and designated thereon by corresponding characters.

The invention comprises a draw-bar 1 having forked ends, one end of which is pivoted on an anchor 2 and the other end of which straddles and receives support on a bar 3 that is positioned transversely at the back of the tractor 4:. The anchor has three upwardly projecting lugs 5 and 66, the former being connected to the pendant lug 7 on the tractor, and'the latter on the housing flanges 8 thereof. The draw-bar is con nected to the anchor by a coupling pin 9.

The bar 3 is secured at its ends by means of bolts 10 to the corresponding pendant ends of a bracket 11 that is mounted upon the tail lug 12 of the tractor, and upon the bracket is positioned a hollow standard 13, the bracket being secured on the tail lug and the standard on the bracket by means of bolts 14; extending therethrough. In the base of the standard is arranged a pinion 15 that has actuating relation with a rack member 16 that extends through the base of the standard and rests upon a ledge 17 on the bracket. The rack member is U-shaped and the lower branch 18 extends between the rear forks of the draw-bar and is attached thereto by a coupling pin 19 so that as the rack member is shifted laterally the draw bar will accordingly be adjustably positioned.

In the pinion 15 is secured a stem 20 that projects from the top of the standard and has fixed thereon a fork 21 and spring 22, and in the fork is pivoted a crank 28 that is sustained by the spring. The crank has a finger 2 1 that normally engages a notched collar 25 on the adjacent end of the standard so as to prevent the crank from turning. In this manner the pinion and rack member and the draw-bar are held in adjusted positions.

In utilizing the invention, a plow or other implement (not shown) is hitched to the draw-bar by a coupling pin 26, and by bearing down upon the crank, the finger 21 is disengaged from the collar so that the crank may be turned and the draw-bar positioned on its support as desired. By removing the pin 19 the draw-bar will have free lateral play on its support.

By thus constructing the apparatus its various parts are easily assembled and applied in position for use uponthe tractor.

. What I claim is 1. In a draft rig for a tractor, an anchor attachable to the tractor body ahead of its rear axle; a supporting member adapted to be positioned on the tail lug of the tractor; a draw-bar coupled at oneend with the anchor and supported at itsopposite end by the memberga Li-shaped rack member detachably connected with the draw-bar; an actuating member for the rack including a through the standard, the bracket and the tail lug securing the same together,

In means forsupporting a laterally movable draw-bar on a tractor, a bracket including it horizontally disposed bar and adapted to be positioned on the tail lug of the tractor; a rack member detachabl y con- 7 nected with the draw-bar; an"aetiiating'fl 10 member for the rack including arstandard;

and ,a pan of bolts extending through the tail lugzand holding the jbraicket a'nd the thereon;
